This improved lubricator is principally de- :which is interiorly'screw-threaded.

Fig. 2 is a top plan view I In referring to the accompanying drawings I m the following explanation indetail of the.

signed. to feed a mixture of oil and graphite, and in order toprevent the graphite from settlingan agitating device is placed directly in the oil-cu itselfjwhich is operated from the same sli'a driving the force-feeding devices.

The oil-cup proper is composed of a cylinder of glass 1,. a to cover or'plate 2 and a e top has a central openbottom plate" 3. ing and a coin aratively large semicircular opening on eac side of said central opening, in one'of which a wire-gauze cage or strainer 41s supported. The top and bottom plates 2 and 3 are .provided with flanges 5 and 5 which fit around the margins 0t the ends of the cylinder, and a packing 6 is'interposed between each'of the plates and the edges of the cylinder.. (See Fig. 1.) The bottom plate has a central projecting portion 7 ,whioh is provided with a vertical recess or soc The componentparts of the oil-cup proper are secured'together by a rod 9, the lower end of which screws into the screw-threaded depression 8 in the bottom plate 3 and the up- 8o per'portion of whiohpassesthroughthe cenketls,

tral opening m-thetop plate- 2 and is screw-i threaded at its projecting end, as fshown at 10 in Figfl, to receivethe lock-ca 11, which screws upon said end- 10.

- The bottom plate 3 has a tubular member which may be formed or cast inte ralwith it, as shown in the accompanyinghe formed separate and attached 1: reto in any well-known way. This tubular memberhas an opening, which is divided into a feeding.

chamber and a valve-chambenj, said chambers being separated by an opening" or reduced diameter.

In the adaptation shown in -the} a panying: drawings the tubular. member is cast integral with the bottom plate;andfoi'ms an enlargement 12, projecting from the bottom of the plate, andsaid enlargement is extended laterally from one side of theb'ottom plate to provide a horizontally-projecting continuation 1'3 of the tubular member.

The horizontal opening which extends through the tubularmember of the bottom plate s divided into a feeding-chamber 14, a

valve-chamber 15, and a short opening 16 of reduced diameter intermediate-the feedingc'hamber and the valvechamber. A ver tical opening 17 extends through the wall of the bottom "plate on one side of the center and forms a passage-way for oil from the .oil-' awings, or-

cup into the .feeding-clmmber and is suffi ciently large to permit the oil to How freely, as shown in Fig. 1. A feeding piston-rod 18 is slidably arranged in the feeding-chamber and projects through the continuation'13 of the tubular member, being reciprocated in a manner hereinafter set forth. The opening -in the outer extremity of the horizontal exwall formed by the reduction of the valvepression of the spring 22.

chamber 15 into the intermediate chamber or opening 16 is formed to constitute a valveseat for a valve-block 21, which islocated in the'valve-chamber 15 and has a tapered end which is normally held. in contact with said seat by a spiral spring 22. The greater portion of the sprin 22 loosely encircles the reduced stem 23 0 the valve-block, and a screw 24, which screws into the inner extremity of the tubular member, is hollow nearly throughout its length to form a socket 25, in which the spring and the stem of the valve-block are housed. The tension of the spring can be regulated by longitudinal adjustment of the screw, and the. end of the screw by striking. a ainst the chamber edge constitutes a stop to imit the movement of the valve-block 21 andprevent excessive com- (See Fig. 1.) The tubularmember is provided with 'a downwardly-extending part26, which-has a .vertical opening 27 extending therethrough and communicating with the valve-chamber 15.

The oil-cup and its feeding mechanism are mounted upon a framewhich is provided with a sight-glass, into which the oil is forced by the feeding mechanism and a second feedmechanism, itS'piston-rod 18, the upper pis' ton rod, and the automatic valve.located in the valve-chamber 15, the upper horizontal valve to distinguish themfrom other and substantially similar mechanisms, to be hereinafter described.

' The frame upon which the oil-cup is sup-.

ported is formed substantially like the frame shown, in my Patent No. 635,694, granted October24, 1899, and has a vertical portionor member 28 provided with a vertical opening 29, III whlch the sight-glass 30 is supported. The lower portion of the opening is reduced in size, as shown in Fig. 1, and a ball valve device is vertically arranged therein. This ball-valve device, which I will hereinafterdesignate as the intermediate vertical valve, is composed of a valvecasing 31,. having an annular valve-seat 32 near its up per end, a ball 33, arranged in the casing and adapted to engage with the seat 32 to close the passage, and a spiral spring 34, arranged to normally maintain the ball in contact with. the seat with a spring tension. Below the vertical portion or member 28 is a horizontal tubular portion or member 35, which has a horizontal opening extending through it and is divided into communicating chambers. One of these chambers 36 is directly below the vertical intermediate valve, withwhich it is connected by a short vertical opening 37 and constitutes an oil-feeding chamber for'a lower feeding mechanism. To the right of the chamber 36 is located a valve-chamber 38,

which isconnected to the feeding-chamber by'a short communicating opening or chainb'er. 39 ofreduced diameter. .This valvechamber is divided into a-plurality of su"ccessively-enlarged sections in each of which a valve device is arranged. A

The valve device in the first section comprises simply a ball 40 and a tension-spring 41 and that in'the second section a valvecasing 42, which has an annular valve-seat 43, a ball 44, and a spring 45 The spring 45 .is secured'in place by a tubular nut 46, which screws in the end of the horizontal portion 35. A piston-rod 47 has one end slid'ably mounted in the oilefeed chamber 36 and is reciprocated substantially as shown in my Patent No. 633,694 by means of a cam ,48, in"

tently rotated by a ball-clutch 52, mounted on a vibratile arm or rod 53, and which in turn is vibrated by any well-known source of 'power-such, for instance, as a connectingrod extending from an operatin portion of an engine. The disk 49 is rotate in only one direction by the clutch 52, being held stationary during the return movement of said clutch by a brake-clutch 54, which is similar in construction to the clutch 52 and mounted upon an arm 55, clamped around the projecting portion 51 of the frame. (See Fig. 5.) The piston=rod 47, which I term the lower piston-rod,isconnected to the upper piston-rod 18 by a verticaL ross-arm 56, so that the two piston-rods are simultaneously reciprocated. This cross-arm is formed integral with and projects vertically from the cam 48, substantially as shown in-Fig. 1,

having an opening 57 near its lower end,

through which the outer portion of the lower piston-rod 47 is fitted, and an upper bifurcated or forked extremity 58, the members of which straddle the central reduced portion valve between the lower feed-chamber '36 and i the sight-glass is to prevent the oil charge in the lower feed-chamber 36 backing up into I the sight-glass during the earlier portion of 59 of a screw-nut .60., which screws upon the knurled lock-nut '62. The obj ect of this is to provide for longitudinal ad j ustinenhof .the

upper piston-rod to regulate the oilfeed, the 6 upper piston-rod being rotated its enlarged knurled end 63 to screw it forward or I 7 portion :82, which extends t back in the nut 60; v

The object of the intermediate vertical the feeding movement of the lower pistonrod; l

The top plate is provided with a trally depending tube 64 and oppositely-extending strengthening-flanges 65 and 66, extending from said tube.

The frame may be provided with a socket .67 forattachment to a suitable support.

The agitating device which is arranged f within the oil-cup, and the agitating portion proper of which. is wholly and directly in said oil-cup, comprises a sleeve 68 and a spiral agitating-strip 69, which encircles and is secured to arms projecting from the sleeve. The sleeve is rotatably mounted upon the vertical rod 9, which thus performs a twofold function, serving to secure the parts of the oil-cuptogether and act ng as a support for the sleeve 68.

The spiral 69 is attached at its upper end to an arm .70, extending laterally from the sleeve 68, and at its lower end to an arm 71,

extending out from the sleeve and substan-.

tially vertically beneath the arm 70, so that the spiral completes one complete spiral turn around the sleeve. The sleeve also has a de-' pending portion 72, which extends on one.

side of the socket 8 to the top surface of the bottom plate'B, and a flat arm 73 extending horizontally'out from the lower extremity of the depending portion 72 and constitutes a scraper which prevents graphite collectin'gon and adhering to the bottom plate. The scraper 73 is connected at its outer end to the outer end of the lower arm 71 by a vertical connection 7 4. The arms and 71, depending portion 72, scraper 73, and connection 74 are all preferably cast integral with I the sleeve 69. The sleeve is rotated by means of gears which are supported in a gearframe mounted on the top plate and are driven from the disk 51 in a manner to be hereinafter described.

The gear-frame consists of a horizontal bottom member 75, which is fastened. to the top plate 2 by screws 76, two vertical memsufiiciently long to project above the top short cen- 1 plate 2 and through the collar 7 9, with the oc'k-cap ll screwing u on the upper extremity 10., extending a ove the collar 7 9- away substantially half of the top of the sleeve 68 for a short distance and likewise cutting away a similar half port-ion from the lower end of the depending portion 82, so as to leave two semicircular projecting ends 83 and 84, which'will extend past each other and lock, thereby preventing rotation of the i sleeve 68 independent of the bevel gearwheel 81.

A horizontal shaft 85 is journaled in the horizontal frame extension and has'a bevelgear-wheel 86 mounted at its inner end, which meshes with the beveled gear' wheel 81. The horizontal shaft is preferably connected to the disk 51, so that the spiral agitating device will be 0 erated from the same powerthat actuates t e force-feed devices. This is preferably accomplished'by fitting a peripheral groove-ring 87 around the disk 49 .and connecting it to a similarly peripheral grooved pulley-wheel 88, mounted shaft 85 by a belt 89.

side of the central opening in the top plate are ,inclosed and covered by semicircular housings 90, which are secured by screws over each 0 ening and have hinge top lids 91,

which may e readily thrownback to expose the opening and permit the cup to be readily filled.

The operation of this improved force-feed lubricator is-as follows: The device being at-- tached to a suitable mechanism or the like requiring lubrication'and the vibratile arm connected to an operating device, 'oil and graphite are poured separately into the oil 1 cup through the separate semicircular openings in the top plate. The outward reci rocatin movement of the upper piston-r0. 18, with rawing said piston into the position shown in Fig. 1, creates a partial vacuum in the feed-chamber 14, so that atmospheric pressure combined with gravity forces a charge of oil from the oil-cup throu h the vertical opening 17 into the feed-cham er 14. The inward movement of the upper pistonrod 18 now forces the oil charge in the feedchamber through the upper. automatic valve and the vertical opening 27 into the sightglass 30. Another outward movement of the two pistons brin s another charge into the upper feed-cham er 14, and the sighton the outer extremity of the horizontal 10o The enlarged semicircular openings on eachglass 30 being loosely set in the member 28, so that air has a chance to enter, the lower piston creates a partial vacuum in the lower feed-chamber 36, so that atmospheric pressure will force a charged oil in the sight glass through the intermediate vertical valve device into the lower feed-chamber 36. The air enters the sight-glass through the semicircular depressions 92, which are formed in the bottom surface of the portion 26. (See Figs. 1 and. 8.) The next inward movement of the two pistons forces the charge of oil in the upper feed-chamber into the sight-glass in the manner before described and the charge of oil in' the lower feed-chamber to any desired lubricating-point. At the same time the intermittent rotation of the disk 51 imparts a like intermittent movement to the horizontal shaft 85 through the belt 89, and.

the horizontal shaft in turn imparts a like intermittent movement to the spiral agitating device through the bevel-gears 81 and 86.

I claim as my invention I 1. In a device of the class described, an

I oil-cup,'a rod located in central vertical position in said oil-cup, an agitator arranged 2. In a device of the class described, a plurality of force-feed devices, a shaft and a cam reciprocated by said' shal't and having a ver tical arm connected to the piston-rod of one of said force-feed devices and an enlargement through which another piston-rod passes.
